When we are conceived it is decided for us physically whether we will be a boy or a girl. Most of us are born as we are and follow the trend of whichever gender was decided for you by genetics. We all have a gender identity, which is a private feeling of whether we are male or female. Two theories as used to explain this. The most influential theory is that our gender is the result of environmental influences. Specifically the way we are raised and treated when we are children by our parents and peers. According to Dr. John Money we are psychosexually neutral at the time of our birth. Only after we have been exposed to the nurture we are exposed to as children does gender set in. The second theory, which seems to be less popular, is that gender is a result of nature or the effect of hormones on the developing brain. When we are born, we are born with either a penis or a vagina. However, long before the child is actually born a process takes place that actually determines whether the child will have male genitalia (a penis) or female genitalia (a vagina). If the child is exposed to a hormone called dihydrotestosterone then male genitalia will be developed. If dihydrotestosterone is not present then female genitalia will develop. In early stages of development male and female genitalia are visually exactly the same. Around 7-8 weeks intrauterine the male organs begin to extend themselves beginning to form looking more like a penis whereas the female genitalia stays relatively the same. At about 12 weeks the genitalia is fully developed and either male or female genitalia is formed (University of Plymouth, 1994-2006). The theory of nature is mainly based on the outcome of the individual’s reaction to certain hormones administered as an infant but signs shown when adult hood is reached. For example, a castrated baby rat is given estrogen when a baby and a baby rat

Between the Sexes, a Great Divide: Respond

...In her article “Between the Sexes, A Great Divide”, Anna Quindlen shows us the differences between the genders, and the divide that exists between them, which starts from the first high school dance, where boys and girls are far away from each other, and all the game is about who is going to do the first move. I mainly agree with Quindlen, but there are some points that I have a different opinion, such as the conclusion is which the writer comes. Only one thing is certain• there are not only differences between men and women, but there are also between ages. The first thing I agree with, is that this gap between the genders is something real. Children, from young age, try all the time to come closer to the other gender, and most of the times, without a good result. It is not the fact that they cannot communicate, but the fact that they are so afraid to make the first move, that they end up saying irrelevant things, which do not help the conversation. The writers says that all of us have the memory of “the first boy-girl” party, in which memory there are boys on one side, and girls on the other. That it totally true. Once I read it, the memory came to my mind very clearly. We all had the same experience in our life, and there are always the shy people, and the braver to make the first move. And in fact, children who used to approach the other gender, had the greater acceptance. So, it is demonstrated that there are nothing to be afraid of the relationships with the other gender...

Business Practices Development

...Best practice does not equal best strategy Benchmarking is an important way to improve operational efficiency, but it is not a tool for strategic decision making. When competitors all try to play exactly the same game, declining margins are bound to follow. PHILIPP M. NATTERMANN The McKinsey Quarterly, 2000 Number 2 Best practice. It may be the most readily recognized and widely used of all business management tools. And why shouldn’t it be? To executives, modeling a company’s performance on its best-in-class competitor is an ambitious but attainable aspiration. To investors, the strategy is a guarantee of the soundness of any company that embraces it. And to consultants, it is the tide that lifts every client’s boat. So why is it killing your margins? Everyone who follows business has seen the fat margins of growing young companies attract scores of new entrants, which eventually crowd the field and drive those very margins down. Why would top executives convert this regrettable fact of business life into a creed, especially when doing so simply hastens the endgame for everyone—first mover and Johnny-come-lately alike? Margins tumble as more and more incumbent companies compete for smaller and smaller segments of customers and industry resources They act as they do because they don’t understand that benchmarking is simply an operational tool. Instead, they all want to occupy the point on the strategic landscape that their most successful competitor has staked out.1 Soon...

Human Cloning

...Differentiation (2002) 69:154–157 C Blackwell Wissenschafts-Verlag 2002 COMMENTARY James A. Byrne ¡ John B. Gurdon Commentary on human cloning Introduction Human cloning refers to the production of genetically identical humans. This cloning is possible via either ‘‘embryo splitting’’ or ‘‘nuclear transfer’’. Embryo splitting involves the separation of an early human embryo into two or more parts. Each of these parts has the potential to develop into a blastocyst (late embryo), which, if implanted, can develop into a child. This is how genetically identical monozygotic twins are created. Artificial embryo splitting has been successfully implemented in various mammals including sheep (Willadsen, 1981), cows (Willadsen, 1989), mice (Agrawal and Polge, 1989) and monkeys (Chan et al., 2000), but has been performed only to the pre-implantation stages in humans (Hall et al., 1993). Recently the American Society for Reproductive Medicine declared that human cloning by artificial embryo splitting was an ethical procedure to increase the number of implantable human blastocysts used in certain infertility treatments (ASRM, 2000). However, embryo splitting can produce only a limited number of cloned individuals as the early embryo can be separated only a limited number of times, and the procedure is not able to produce a ‘‘clone’’ of an adult that already exists. The other method for producing cloned humans, nuclear transfer, does not suffer from these limitations, and the rest...

Controversies of Stem Cell Research

...ABSTRACT Stem cells have offered much hope by promising to greatly extend the numbers and range of patients who could benefit from transplants, and to provide cell replacement therapy to treat debilitating diseases such as diabetes, Parkinson's and Huntington's disease. The issue of stem cell research is politically charged, prompting biologists to begin engaging in ethical debates, Stem cell research offers great promise for understanding basic mechanisms of human development and differentiation, as well as the hope for new treatments. However, human stem cell research also raises sharp ethical and political controversies. This paper will discuss the types of stem cells as well as some of the controversies involved in stem cell research. Introduction According to Wikipedia, stem cell can be defined as “biological cells found in all multicellular organisms, that can divide (through mitosis) and differentiate into diverse specialized cell types and can self-renew to produce more stem cells.” A stem cell could be regarded as one of the basic building blocks of the human body. Stem cells are important because they have the ability to become different cell types, and scientists are working on developing ways to use stem cells to repair or regenerate damaged organs or tissues. This could lead to therapies for a whole range of conditions such as heart disease, diabetes, Parkinson's disease or Alzheimer's, although at present it is impossible to tell whether this will happen...

Human Embryonic Stem Cells

...Introduction Human embryonic stem cells (hES cells) are currently discussed not only by the biologists by whom they were discovered but also by the medical profession, media, ethicists, governments and politicians. There are several reasons for this. On the one hand, these ‘super cells’ have a major clinical potential in tissue repair, with their proponents believing that they represent the future relief or cure of a wide range of common disabilities; replacement of defective cells in a patient by transplantation of hES cell‐derived equivalents would restore normal function. On the other hand, the use of hES cells is highly controversial because they are derived from human pre‐implantation embryos. To date, most embryos used for the establishment of hES cell lines have been spare embryos from IVF, but the creation of embryos specifically for deriving hES cells is also under discussion. The most controversial variant of this is the transfer of a somatic cell‐nucleus from a patient to an enucleated oocyte (unfertilized egg) in order to produce hES cells genetically identical to that patient for ‘autologous’ transplantation (so‐called ‘therapeutic’ cloning); this may prevent tissue rejection. The question ‘Can these cells be isolated and used and, if so, under what conditions and restrictions’ is presently high on the political and ethical agenda, with policies and legislation being formulated in many countries to regulate their derivation. The UK has been the first to pass...

Market Segmentation

...segmentation by personality type, you can create personality type. This knowledge of individual preferences related to a respondent’s personality can be leveraged to create more effective marketing campaigns and increase sales. Market segmentation is a marketing strategy that involves dividing a broad target market into subsets of consumers, who have common needs, and then designing and implementing strategies to target their needs and desires using media channels and other touch-points that best allow to reach them. Market segmentation involves dividing up the potential market for a product into groups of people who have similar needs, and then addressing these needs in a focused way. Market segments allow companies to create product differentiation strategies to target them. The concept was introduced in early 1960’s not just to advertise but also bring about product innovation, pricing, choice of distribution channels etc. A broader aspect of segmentation is the term psychographics. Psychographic profiles are used in market segmentation as well as in advertising. Psychographics is...

Acute Renal Failure

...A stem cell is an immature cell that has the potential to become specialized into different types of cells throughout the body. There are two basic types of stem cells: adult stems cells and embryonic stem cells. Embryonic stem cells are produced when a newly fertilized egg begins to divide. These stem cells can become any type of cell in the body. Adult stem cells are undifferentiated cells found throughout the body that divide to replenish dying cells and regenerate damaged tissues. Both types of cells are of great interest to medicine and science because of their ability to develop into virtually any other cell made by the human body. In theory, if stem cells can be grown and their development directed in culture, it would be possible to grow cells of medical importance such as bone marrow, neural tissue or muscle. The ability to grow human tissue of all kinds opens the door to treating a range of cell-based diseases and to growing medically important tissues that can be used for transplantation purposes. For example, diseases like juvenile onset diabetes mellitus and Parkinson's disease occur because of defects in one of just a few cells types. Replacing faulty cells with healthy ones offers hope of lifelong treatment. Similarly, failing hearts and other organs, in theory, could be shored up by injecting healthy cells to replace damaged or diseased cells. In vitro fertilization is a process whereby human life is generated in a laboratory environment such as a glass petri...

Bags of groceries hang from the handles and any other protrusion that can serve as a hook. He is accompanied by an older woman who walks behind him; one hand gripping her own load of bags while the other rests lightly on the back of the chair. They stop once they are near me and I get a clear look at the occupant of the chair. He is a young a man. Thin, emaciated arms and legs are drawn in toward his body. It is clear that he has been confined to this chair for a long time. The woman is his mother and she asks me if I can watch him while she goes into a nearby building to call a friend to give them a ride. I agree and she leaves me with her son. I strike up a casual conversation, looking him in the eye and being careful not to talk down to him. His speech is labored and slurred. He is suffering from cerebral palsy. His mother returns and thanks me; her friend is his way to help. I go about my business realizing that I have no problems in my life when compared to that young man. My body is sound. Imagine being trapped in your body like that. Then realize that there is a real potential for a cure, but no one is allowed to work on it. Embryonic stem cell research has the potential to cure that young man and thousands like him. Perhaps it is time to we lifted the unrealistic restrictions that have held this research back for so many years? Embryonic...
